DETAILED DESCRIPTION

With reference now to the FIGS., an example of a cooking system 20 isillustrated at numeral 20. As best shown in FIGS. 1 and 2, the cookingsystem 20 includes a housing 22 having an exterior heat resistant ornon-conductive surface 24 and an interior surface 26 that defines an atleast partially hollow compartment 28 arranged within an interior of thehousing 22. The housing 22 may be formed as a single unitary body, oralternatively, may be formed by connecting a plurality of piecestogether. In addition, the housing 22 may be made of any suitablematerial, including but not limited to glass, aluminum, plastic, orstainless steel for example. A liner 30 may be disposed within at leasta portion of the housing 22. The liner 30 may be formed from anysuitable conductive material, such as aluminum for example. In anembodiment, the liner 30 forms at least a portion of the interiorsurface 26 and thereby defines at least a portion of the internalcompartment 28 of the housing 22. However, it should be understood thatother components of the cooking system 20, or surfaces thereof, may alsodefine the internal compartment 28.

A cooking container 32 is receivable within a portion of the internalcompartment 28 of the housing 22, such as a bottom portion of theinternal compartment 28 for example. Although the cooking container 32is described herein as being separable from the housing 22, embodimentswhere the cooking container 32 is movably connected with or integrallyformed with the housing 22 are also contemplated herein. The cookingcontainer 32 may be a pot formed from a ceramic, metal, or die castaluminum material. However, any suitable material capable ofwithstanding the high temperatures required for cooking food productsare also within the scope of the disclosure. In an embodiment, thecooking container 32 is configured to translate along an axis relativeto the housing 22 such that the cooking container 32 is slidablyreceived within an opening 34 formed in a wall 36 of the housing 22.Accordingly, in such embodiments, a size and shape of the cookingcontainer 32 may be complementary to the size and shape of the opening34. In the illustrated, non-limiting embodiment, the cooking container32 is generally square in shape. However, in other embodiments, thecooking container 32 may have another configuration.

The cooking container 32 has a generally hollow interior 38 forsupporting one or more consumable products, such as food products forexample, therein. Examples of food products suitable for use with thecooking system 20, include but are not limited to, meats, fish, poultry,bread, rice, grains, pasta, vegetables, fruits, and dairy products,among others.

At least one handle 40 may be associated with the cooking container 32to allow a user to easily grasp and manipulate the cooking container 32relative to the housing 22. In the illustrated, non-limiting embodiment,the cooking container 32 includes a single handle 40 extending from afirst, front surface 42 of the cooking container 32. Although thecooking container 32 illustrated and described herein has a singlehandle 40, in other embodiments, the cooking container 32 may have twoor more handles, or alternatively, a handle or groove formed into asurface of the cooking container 32. Any suitable configuration of thecooking container 32 and/or handle(s) 40 is within the scope of thedisclosure.

One or more inserts or food support structures 50 may be positionablewithin the interior 38 of the cooking container 32. In such embodiments,the insert 50 provides a surface on which food is supported. An exampleof an insert 50 suitable for use with the cooking container 32 is bestshown in FIGS. 4 and 5. As shown, the insert 50 includes a solidblocking wall 52 and a food support surface 54 having a plurality ofperforations or openings 56 formed therein. In the illustrated,non-limiting embodiment, the blocking wall 52 and the food supportsurface 54 are arranged generally perpendicular to one another. Althoughthe insert 50 is shown as being an L-shaped plate, in other embodiments,the insert 50 may include additional side walls such that the insert 50is a basket for example. When the insert 50 is installed within theinterior 38 of the cooking container 32, the blocking wall 52 and thefood support surface 54 of the insert 50 cooperate with one or morewalls of the cooking container 32 to define an area there betweenreferred to herein as a “cooking volume.” Further, in embodiments wherean insert is not disposed within the cooking container 32, the interior38 of the cooking container 32 may define the cooking volume.

In the illustrated, non-limiting embodiment, the bottom surface 58 ofthe cooking container 32 is sloped relative to a bottom surface of thehousing 22 or to a surface on which the cooking system 20 may bepositioned and supported. As shown, the slope extends generally upwardlytowards a front wall 60 of the cooking container 32. As a result, aheight of the interior 38 of the cooking container 32 adjacent a backwall 62 is greater than a height of the interior 38 of the cookingcontainer 32 adjacent the front wall 60 thereof. When the insert 50 isinstalled within the interior 38 of the cooking container 32, the foodsupport surface 54 has a generally horizontal orientation. As shown, theinsert 50 may include one or more protrusions 64, such as tabs forexample, configured to contact the bottom surface 58 of the cookingcontainer 32 to achieve this desired orientation. The food supportsurface 54 is therefore at least partially offset from the bottomsurface 58 of the cooking container 32. Because of the angledconfiguration of the bottom surface 58 of the cooking container 32, theclearance 66 between the bottom surface 58 and the food support surface54, varies, and more specifically, gradually decreases from a back to afront of the cooking container 32.

The insert 50 and the bottom surface 58 of the cooking container 32 maycooperate to properly position the insert within the interior 38 suchthat the blocking wall 52 of the insert 50 is offset from the back wall62 of the cooking container 32. This clearance between the blocking wall52 and the back wall 62 defines an air duct 74 within the cookingcontainer 32, separate from the cooking volume, and through which air iscirculated during operation of the cooking system 20. In an embodiment,a contour of the cooking container 32 facilitates positioning of theinsert 50 relative to the cooking container 32. As previously described,one or more protrusions 64 extend from a bottom surface of the insert50, and as best shown in FIGS. 4 and 5, the bottom surface 58 of thecooking container 32 may be contoured to define one or more channels 68therein. When the insert 50 is positioned within the cooking container32, the one or more protrusions 64 are received within the one or morechannels 68. The engagement between the at least one protrusion 64 andthe sidewalls of the channel(s) 68 properly positions the insert 50within the cooking container 32 to create a suitably sized air duct 74.

The cooking system 20 additionally includes at least one heating element70 operable to impart heat to the cooking volume during one or moremodes of operation of the cooking system 20. In the illustrated,non-limiting embodiment best shown in FIGS. 1, 2 and 4-5, the at leastone heating element 70 is positioned within the internal compartment 28,generally at or above an upper extent or surface 72 of the cookingcontainer 32, such as proximate a center of the cooking container 32 forexample. In an embodiment, the heating element 70 is disposed adjacent acenter of the cooking volume and/or the cooking container 32. In suchembodiments, the at least one heating element 70 is mounted completelyoutside of the cooking container 32, and vertically offset from theupper extent or surface 72 thereof. In another embodiment, best shown inFIG. 3, the at least one heating element 70 may be located adjacent therear of the internal compartment 28, such as in vertical alignment withthe air duct 74 formed between the blocking wall 52 of the insert 50 andthe back wall 62 of the cooking container 32. However, it should beunderstood that a heating element 70 located at any suitable location iswithin the scope of the disclosure.

The at least one heating element 70 may be capable of performing anysuitable type of heat generation. For example, a heating element 70configured to heat one or more food items located within the cookingvolume of the cooking container 32 via conduction, convection,radiation, and induction are all within the scope of the disclosure. Inthe illustrated, non-limiting embodiment, the heating element 70 is aconvective heating element, and the cooking system 20 additionallyincludes an air movement mechanism 76, such as a fan for example,operable to circulate air through the cooking volume. The air is heatedas it flows along a path of circulation, such as by flowing over aportion of the at least one heating element 70. As shown, the airmovement mechanism 76 is located within the internal compartment 28 at aposition entirely above the upper extent 72 of the cooking container 32.In addition, at least a portion of the air movement mechanism 76, and insome embodiment, the entirety of the air movement mechanism 76, isdisposed vertically above the cooking volume, and therefore the insert50. As shown, the air movement mechanism 76 is horizontally offset fromthe at least one heating element 70. However, embodiments where the airmovement mechanism 76 vertically or horizontally overlaps or is alignedwith the at least one heating element 70 are also contemplated herein.

The air movement mechanism 76, or at least a portion thereof may beremovable from the internal compartment. In the illustrated,non-limiting embodiment, the air movement mechanism 76 is driven by amotor 78 located at least partially externally to the internalcompartment 28. Further, the cooking system 20 may include a vent 80 forexhausting hot air generated by operation of at least one of the airmovement mechanism 76 or the motor 78 to the exterior of the cookingsystem 20. Although the vent 80 is illustrated as being formed at therear of the internal compartment 28, embodiments where the vent 80 isformed at another location are also contemplated herein.

An example of the air movement mechanism 76 is illustrated in moredetail in FIGS. 5 and 6. In the illustrated, non-limiting embodiment,the air movement mechanism 76 includes a fan wheel 82 positioned withina fan housing 84. As shown, the fan wheel 82 is configured to rotateabout an axis X oriented generally horizontally, and in someembodiments, the axis of the fan wheel is oriented perpendicular to thetranslational axis along which the cooking container 32 is configured tomove relative to the housing 22. The fan housing 84 has an outer wall 86having a scroll-shaped length, a first sidewall 88 including a firstinlet aperture 90 and a second sidewall (not shown) including a secondinlet aperture. Although the outlet opening 92 of the fan housing 84 isillustrated as being generally rectangular in shape, embodiments wherethe outlet opening 92 is another shape are also contemplated herein.

With specific reference now to FIG. 6, the fan wheel 82 is typicallyformed with first wheel portion 94 and a second wheel portion 96. Boththe first wheel portion 94 and the second wheel portion 96 function asan air inlet and are configured to provide air to a single plenum. Theair inlet defined by the first wheel portion 94 is arranged in a firstplane at a first side of the air movement mechanism 76 and the air inletdefined by the second wheel portion 96 is arranged in a second plane ata second side of the air movement mechanism 76, the first and secondplanes being generally parallel. Accordingly, the air inlets defined bythe first and second wheel portions 94, 96 remain generally fixedrelative to both the fan housing 84 and an axis of rotation of the fanwheel 82. The first wheel portion 94 includes a first plurality ofimpeller blades 98 and the second wheel portion 96 similarly includes asecond plurality of impeller blades 100. One or both of the firstplurality and the second plurality of impeller blades 98, 100 may have abackward curved configuration, a forward curved configuration, oranother configuration.

With reference now to FIG. 7, a control panel or user interface 102 maybe positioned at an exterior surface of the housing 22. The controlpanel 102 includes one or more inputs 104 associated with energizing theheating element 70 of the cooking system 20 and for selecting variousmodes of operation of the cooking system 20. One or more of the inputs104 may include a light or other indicator to show that the respectiveinput has been selected. The control panel 102 may additionally includea display 106 separate from and associated with the at least one input104. However, embodiments where the display 106 is integrated into theat least one input 104 are also contemplated herein.

Operation of the one or more inputs 104 will be described in more detailbelow. FIG. 7 illustrates an example of a control system 108 of thecooking system 20 including a controller or processor 110 forcontrolling operation of the heating element 70 and air movement device76 (including the motor 78 associated therewith), and in someembodiments for executing stored sequences of heating operation. Theprocessor 110 is operably coupled to the control panel 102 and to theheating element 70 and the air movement mechanism 76.

In addition, the cooking system 20 may include one or more sensors S formonitoring one or more parameters associated with the temperature of theheating element 70, the cooking volume, the airflow being delivered tothe cooking volume and/or and the insert 50 positioned within thecooking container 32 during a cooking operation. Accordingly, operationof the cooking system 20, and in particular of the one or more heatingelements 70, may be regulated in response to the parameters sensed bythe one or more sensors S. In an embodiment, the one or more sensors Sincludes a temperature sensor arranged in communication with theprocessor 110. In an embodiment, the temperature sensor(s) S, such as anegative temperature coefficient (NTC) sensor for example, is positionedadjacent the rear of the internal compartment 28, upstream from the airduct 74 defined between the back wall 62 of the cooking container 32 andthe blocking wall 52 of the insert 50. In embodiments of the cookingsystem 20 including one or more temperature sensors S, adjustment of anoperating parameter, such as operation of the heating element 70 forexample, may be performed using the control algorithm in response to thetemperature of the heated airflow, measured by the temperature sensor Sdisposed in the heated airflow. For example, power provided to theheating element 70 may be increased if the sensed airflow temperature isbelow a set point, and the power provided to the heating element 70 maybe reduced or ceased completely if the sensed airflow temperature isabove a set point, thereby allowing the cooking volume to cool.

In an embodiment, the air movement mechanism 76 of the cooking system 20is a variable speed fan operable at a plurality of rotational speeds. Inan embodiment, the operational speed of the air movement mechanism 76may vary based on the cooking mode selected. For example, the speed ofthe air movement mechanism 76 during operation in a first cooking modemay be different than the speed of the air movement mechanism 76 duringoperation in a second cooking mode. The operational speed of the airmovement mechanism 76 may be controlled by the processor 110 in responseto one or more inputs 104, including selection of a cooking mode.However, the processor 110 may also be configured to adjust theoperational speed of the air movement mechanism 76, or alternatively,the power supplied to the at least one heating elements 70 to controlthe temperature and/or pressure within the interior 38 of the cookingcontainer 32.

In an embodiment, at least one input 104 on the control panel 102 is anon/off button which allows the user to activate or deactivate thecontrol panel 102. When the control panel 102 is deactivated, the one ormore heating elements 70 are not energized. In an exemplary embodiment,the at least one input 104 is operable to select one or more manualmodes of operation of the heating element 70. Alternatively, or inaddition, at least one input 104 is operable to select a stored sequenceof operation of the heating element 70. In some cases, the storedsequences may be particularly well suited for a given method of foodpreparation and/or for particular ingredients or types of ingredients.The plurality of stored sequences associated with the at least one input104 may be stored within a memory accessible by the processor 110.Alternatively, the plurality of stored sequences may be stored remotelyfrom the cooking system 20, and may be accessed by the processor 110,such as via wireless communication for example.

In addition, a user may be able to enter a time associated withoperation of the cooking system 20 in a desired manual mode. The timemay be entered via the same input 104 or a separate input 104 as used toselect a mode of operation. Further in embodiments where the cookingsystem 20 is in a mode configured to perform a stored sequence inresponse to selection of one of the inputs 104, the display 106 mayindicate a time remaining. Temperature or other parameters may also beentered via inputs 104 and/or shown on the display 106.

The at least one input 104 may include a distinct start button intendedto initiate operation in a desired mode, a distinct stop button to ceaseall operation, or a stop/start button intended to initiate and ceasefunctions. Alternatively, the cooking system 20 may be operable toautomatically start operation after a predetermined time has elapsedonce an input 104 has been selected and any necessary information hasbeen provided to the control panel 102. Alternatively, one or more ofthe other inputs 104 may be operable to start and stop operation of thecooking system 20, regardless of whether the cooking system 20 isfollowing a stored sequence or is in a manual mode.

As previously noted, the one or more inputs 104 may be operable toinitiate operation of the cooking system 20 in a plurality of cookingmodes. In an embodiment, the cooking system 20 is operable in a cookingmode where the heating element 70 is employed to perform a non-contactheating operation, such as a convective or radiative heating operation.Suitable cooking operations that may be performed in this first cookingmode include, but are not limited to air frying, broiling,baking/roasting, and dehydrating.

During operation in the first cooking mode, the air movement mechanism76 is operable to circulate a heated air flow through the cookingvolume. As previously described, the air movement mechanism 76 isoperable to draw air upwards, through the adjacent heating element 70and into the two inlets arranged at opposing sides of the fan wheel 82.The heated air is expelled outwardly from the outlet opening 92 of thefan housing 84 in a single direction. In the illustrated, non-limitingembodiment, the air output from the air movement mechanism 76 isprovided within a plane directed downwardly into the cooking container32. In the illustrated, non-limiting embodiment, the outlet opening 92arranged directly adjacent the upper extent 72 of the cooking container32, such that the air is expelled from the outlet opening 92 directlyinto the air duct 74 formed within the cooking container 32. Once theheated air reaches the bottom surface 58 of the cooking container 32,the hot air will be deflected off the bottom surface 58 towards thecooking volume. Because the bottom surface 58 of the cooking container32 is sloped, the interaction between the heated air and the slopedbottom surface 58 directs the heated air both forwards and upwardly,causing the air to evenly distribute from the back to the front of thecooking container 32 before passing through the openings 56 formed inthe food support surface 54 of the insert 50. The hot air is drawn bythe air movement mechanism 76 through the openings 56 and over theexterior of the food items positioned on the food support surface 54.From within the cooking volume, the air is then drawn back into one ofthe inlets of the air movement mechanism 76 for further circulationwithin the interior 28.

With reference now to FIGS. 8-15, in an embodiment of the cooking system20, the housing 22 includes a plurality of internal compartmentsarranged within the interior of the housing 22. For example, as bestshown in FIGS. 8, 14, and 15, the housing 22 is illustrated as having afirst internal compartment 28 a and a second internal compartment 28 b,separated from one another at least in part by a divider or wall 130.The divider 130 extends vertically from a base of the housing or liner30 and forms a sidewall of a bottom portion of two adjacent internalcompartments 28 a, 28 b. In an embodiment, the divider 130 extends to alower edge of an upper portion of each internal compartment 28 a, 28 b,the upper portion of each internal compartment containing the respectiveheating element 70 a, 70 b, and air movement mechanism 76 a, 76 bassociated therewith. As shown, the plurality of internal compartments28 a, 28 b (both the upper and lower portions) are fluidly separate fromone another. Although two internal compartments 28 a, 28 b areillustrated and described herein, it should be understood thatembodiments including any number of internal compartments, such as morethan two compartments are also within the scope of the disclosure. Theplurality of internal compartments 28 a, 28 b may be substantiallysimilar in size and shape, or alternatively, may be different.

Each of the internal compartments 28 a, 28 b formed in the housing 22may be substantially identical to the internal compartment 28 previouslydescribed with respect to FIGS. 1-6. More specifically, a respectivecooking container 32 a, 32 b is insertable into each internalcompartment 28 a, 28 b, and an insert 50 a, 50 b may be removablyinstalled within the interior 38 a, 38 b of each cooking container 32 a,32 b. In addition, each internal compartment 28 a, 28 b includes atleast one heating element 70 a, 70 b and an air movement mechanism 76 a,76 b configured to circulate air through the internal compartment 28 a,28 b, respectively. The components associated with operation of eachinternal compartment, such as the heating element and air movementmechanism are also independently operable and fluidly separate from thecomponents of the adjacent internal compartment.

In the non-limiting embodiment of FIGS. 14 and 15, each air movementmechanism 76 a, 76 b is illustrated as a fan wheel or impeller 82 thatis configured to rotate about a generally vertically oriented axis. Theair movement mechanisms 76 a, 76 b need not include a separate housingas previously described with respect to the embodiment of FIGS. 1-6. Asshown, the air movement mechanisms 76 a, 76 b may be stacked verticallyrelative to the heating element 70 a, 70 b such that a flow of air isconfigured to flow from the heating element 70 a, 70 b directly to theair movement mechanism 76 a, 76 b sequentially. The axial flow of airprovided to the inlet of the air movement mechanism 76 a, 76 b isexpelled from the impeller 82 a, 82 b radially, adjacent the sides ofthe internal compartment 28. Although this configuration of the airmovement mechanism 76 a, 76 b is illustrated with respect to anembodiment of the cooking system 20 including a plurality of fluidlydistinct internal compartments 28 a, 28 b, it should be understood thatsuch an air movement mechanism 76 may also be used in embodiments of thecooking system 20 including only a single internal compartment 28.

As noted above, the cooking system 20 includes a motor 78 locatedexternal to the internal compartment 28 and operable to rotate an airmovement mechanism 76 about an axis of rotation X. In embodiments of thecooking system 20 including two distinct internal compartments, a singlemotor 78 may be used to drive both a first air movement mechanism 76 aassociated with the first internal compartment 28 a and a second airmovement mechanism 76 b associated with the second internal compartment28 b. In such embodiments, the motor 78 may be disposed within thehousing 22 between the first and second compartments 28 a, 28 b, suchthat the first air movement mechanism 76 a is mounted to a first outputshaft 120 extending from a first side of the motor 78 and the second airmovement mechanism 76 b is mounted to a second output shaft 122extending from a second side of the motor 78. As a result, the first airmovement mechanism 76 a and the second air movement mechanism 76 b maybe positioned coaxially (see FIG. 10). However, embodiments, where theaxis of rotation X1 of the first air movement mechanism 76 a is offsetfrom the axis of rotation X2 of the second air movement mechanism 76 bare also contemplated herein.

Because a single motor 78 is used to drive the both the first and secondair movement mechanisms 76 a, 76 b, in an embodiment, both the first andsecond air movement mechanisms 76 a, 76 b are driven about their axes,even when only one of the first and second internal compartment 28 a, 28b is being used to perform a cooking operation. Accordingly, an airmovement mechanism 76 may rotate about its axis even when the adjacentheating mechanism 70 associated therewith is non-operational. In otherembodiments, the first and second air movement mechanisms 76 a, 76 b maybe independently operable via a shared motor 78. Further, in anembodiment, the motor 78 is operable to rotate the first and second airmovement mechanisms 76 a, 76 b, at the same speed. However, embodimentswhere the first and second air movement mechanisms 76 a, 76 b, arerotated at different speeds, such as via a coupling for example, arealso within the scope of the disclosure.

However, it should be understood that embodiments of the cooking system20 that include a separate motor associated with each internalcompartment are also within the scope of the disclosure. For example, asshown in FIG. 15, the system 20 includes two separate motors 78 a, 78 bconfigured to operate the air movement mechanisms 76 a, 76 b associatedwith the first and second internal compartments 28 a, 28 bindependently. In such embodiments, each motor 78 a, 78 b may be locatedexternal to the internal compartment 28, for example in a verticallystacked configuration relative to the heating elements 70 a, 70 b, andthe air movement mechanisms 76 a, 76 b. In such embodiments, the motors78 a, 78 b may be located near an upper end or top surface of thehousing 22.

In embodiments of the cooking system 20 including a plurality ofinternal compartments, a single control system 108, as previouslydescribed with respect to FIG. 7, may be suitable to selectively performone or more cooking operations associated with both the first internalcompartment 28 a and the second internal compartment 28 b. Accordingly,the same inputs 104 may be used to provide control for the plurality ofinternal compartments 28 a, 28 b, or alternatively, distinct inputs 104may be associated with each of the plurality of internal compartments 28a, 28 b, respectively.
